EMERY M. HAMILTON, on NEW YORK, N. Y.

TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 357,671, dated February 15, 1887.

Application filed August 25, 1884. Renewed December 2, 1886. Serial No. 220,532. (No model.)

To all whom it may concern:

Be it known that I, EMERY M. HAMILTON, of the city of' New York, in the county and State of New York, and a citizen of the United States of America, have invented a new and useful Improvement in Type-VVriting Machines, of which the following is a specification, reference being had to the accompanying drawings, forming part of the same,in which- Figure 1 is a plan view of the paper-carrier of a printing-machine containing my invention, and the frame in which it is mounted to slide, together with a part of the face of the printing-machine, with which the said frame is connected. Fig. 2 is a similar view of the said frame and carrier detached from the machine, showing the carrier swung over on its hinges or pivots to expose to view the under side of the same. Fig. 3 is a right-hand end elevation of the said carrier and a cross section of the'said framerand Fig. 4 is a lefthand elevation of the said carrier and frame.

The general construction of the printingmachine upon which I employ the herein-described carr'ier is described and shown in the specification and drawings accompanying my application for Letters Patent filed in the United States Patent Office March 13, 1884., consisting of a series of type-bearing levers arranged radially in a horizontal or nearly horizontal plane around a circle, that are operated by keys from which motion is commu: nicated'through suitable intermediate mechanism, to throw the inner or type end of the lever to the center of the system, where the printing-impression is made.

My present invention relates to the carrier, by means of which the paper to be printed upon is moved over the face of the machine in 0 the act of printing; and it consists in the devices herein described and claimed.

A is the face of the machine; B, the circle of type-levers, only four being shown. It will be understood that the front side of the machine is indicated by the irregular line as x, the key-board supposed to be removed. (Not shown.)

G is a frame formed of side bars, a a, and cross-bars, b b. This frame is hinged or pivoted at its rear edge, as at c c, to posts that rise from the face of the machine, so that its position may be reversed to expose to View its under side.

In grooves formed on the inner edges of the side bars, a a, is fitted to slide a frame or plate, D. On this frame or plate are mounted the feed-rollers E F, which are journaled in end pieces 6 c, that are tied together by the bar f and the axial shaft 9 of the feed-roller F, the said end pieces 6 e, barf, and axial shaft 9 forming a frame carrying said feed-rollers. This frame is pivoted or hinged at its front edge to posts h h, that rise from the end pieces 2' z" of the frame D, by means of screws j j, which pass through the posts h h into recessed openings in the outer faces of the front ends of the end pieces e 0. By means of this arrangement the said frame, together'with the feed-rolls E F, may be laid down-upon the frame D, thus bringing the tablet G (which is connected with the inside face of the frame carrying the feed-rollers, and upon which the printing-impression is made by the type on the end of the type-levers) immediately over the center of the system of type-levers, as shown in Fig. 1, and permitting it at pleasure to be rocked over toward the front of the machine, thus reversing its position, as shown in Fig. 2, in which position the paper to be printed upon may be readily and conveniently introduced into the machine by inserting its edge between the rollers and turning the roller E, by means of the finger-piece k on the axis of said roller. hen the paper is thus introduced, the frame carrying the rollers is rocked over back intoits first position, (shown in Fig. 1,) when the paper and the machine are in position to commence the operation of printing.

The frame carrying the rollers is held in position down upon the frame D, as seen in Fig. 4

1, by means of a leaf-spring, Z, secured to and projecting a little above the end 3 of frame D, and a stud, m, in the end piece 6, the spring being provided with a countersink near its outer end, into which the conical end of the stud m takes.

It will be understood that the machine is provided with suitable feed mechanism, acting in conjunction with the toothed bar H on the frame D, whereby, by means of motion 5 communicated from the keys, (not shown,) the frame D, carrying the feed-rolls, is moved step by step from left to right to present the paper to the type in the act of printing. As my present invention does not relate to such :0 feed movement, I have not deemed it necessary to describe it particularly or exhibit it in the drawings. The same will be found fully described and shown in the specification and drawings accompanying my application r5 for a patent for improvement in type-writing machines filed June 30, 1884, Serial No. 136,491.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is-

In a type-writing machine, the combina- 20 tion, with the sliding frame D, of aframe carrying thefeed-roilers hinged or pivoted to said frame D, as described, so that when it is swung upward upon its pivot it will be turned toward the operator, as and for the purpose 25 specified.
